      the bios you posted is empty... remove the bios chip from the board before writing or reading, put it in the adapter and then in the programmer, if you don't have anything to remove it with, solder wires between the chip and the programmer... post the content again..

          I removed the BIOS chip and used the RT809F to read it. When I read it, I got an empty file as shown above. I tried to erase the chip but it didn't work. I have replaced the BIOS chip with a new one and need to find a clean boot file. Thank you.

                      Good morning, unfortunately the equipment does not generate an image.
                      By chance they have the file available for the EC​

                                      ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
                                      by DynaxSC
                                      Hi

                                      I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
                                      The SPI chip is an Winbond 25Q256JWEQ model (1V8).
                                      The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
                                      The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

                                      I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

                                      [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
                                      by hyperwood
                                      Hi everyone,

                                      I’m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

                                      The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

                                      I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip – and the last 2MB in those files are just FF FF FF....

                                      ✅ What I need:
                                      • A working 2MB BIOS dump
                                      • Matching NM-E471 Rev. 2.0, e.g. JY575
                                      ...

                                      NT955XED (Samsung Galaxy Book2 Pro - 15.6) BIOS dump file Request
                                      by Citymin
                                      Hi all,

                                      My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
                                      The charging red LED lights up, but the charging screen doesn't show any indication.
                                      When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
                                      (I've tried removing the battery and resetting the device, but the issue persists.)

                                      NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)

                                      I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the command
                                      Code:

                                      it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

                                      The trouble I'm having is that I'm not getting the newly...
